Researchers Develop Breakthrough Field-Effect Transistor (FET) with Graphene

Sweden's Chalmers University researchers demonstrated a graphene-based transistor design that allows more compact RF mixer processing. This could very well be a breakthrough, because it not only allows designing much more compact radio-frequency electronics, but also allows circuits to run faster. This could accelerate the development of Terahertz electronics systems whose applications include radar, radio astronomy, and process monitoring. Its developers have named it G-FET, or Graphene field-effect transistor. An allotrope of carbon, graphene is an honeycomb lattice of carbon atoms on an atomic-scale. It is electrically-symmetrical, giving it the ability to act as electron or hole carrier. This means that a single G-FET can act as an RF mixer without needing the feeding circuits used in current designs.

I watched something just the other dan on nanotube RF potential. One step closer to man made silicon-like products maybe.

So long as it makes my graphics cards faster!!! :nutkick::roll:

Yeah me to on Netflix.. There was section on pencil being used and nano tubes. And i think this is just that by the name pencil so think of how thin it is when you wright on a piece of paper and much thinner that could be.

The limits of current chip production are coming so soon (below 10nm?) and it excites me so much as whatever comes next is going to be so much more advanced and i love seeing all the learning and advancement that is being made on the atomic and even sub atomic scale as one or more of these new technology's will be used to make much much more advanced circuits giving so much more computer power and storage along with all the other advances in other areas of electronics.

I kind of expect the upcoming jumps in computer tech to be relatively like going from vacuum tube transistors to transistors on silicone chips.

Oh certainly. I've been catching articles here and there for years about some of the new ideas they've been coming up with. Some of the stuff is just radical, but at the same time plausible. Advancements would be dramatic.

Think my favorite story I caught, maybe a few years ago, was the one where they were working on the ability to store data in light itself. After all, light can become more than one form. Fascinating since it made all those sci fi shows with data being stored in glowing crystals/etc, actually not too far off.

No, it's actually a NOVA program called Making Stuff ( in this case the episode was Making Stuff Smaller.
I watched that recently also. The one with the eyeball "robot" and also talked about nylon and kevlar too. Good show. Now I need to catch up on the Anunnaki and stop trolling. :toast:
